Complete Low-Voltage and High-Voltage Switchgear Power-On Test Bench Main Features:
(1) Integrates multiple AC and DC power supplies, facilitating the testing of switchgear and greatly improving work efficiency.
(2) Uses independent transformers and voltage regulators for boosting (current), avoiding damage to the voltage regulator.
(3) Primary components inside the box adopt products from well-known domestic brands; measuring instruments for current, voltage, frequency, etc., use 0.5-class digital meters, and sensors (current transformers, voltage transformers) use 0.5S class.
(4) Uses anodized brushed aluminum panel, wear-resistant, dirt-resistant, and more aesthetically pleasing.

III. Instructions for Use:
1. Connect three-phase four-wire AC 380V
2. Connect the output DC 300V to the load
3. Rotate the output adjustment knob counterclockwise to zero.
4. Check and confirm the wiring is correct
5. Close the power switch
6. Slowly adjust the output adjustment knob to raise the voltage to a suitable value.
7. After the test is completed, first rotate the output adjustment knob counterclockwise to zero, then turn off the power switch. Only after the discharge is complete can you start disconnecting the wires.
